Ultrasound
Scanning
I
offer a competitively priced Ultrasound scanning service to determine pregnancy in bitches.
This service can be offered in your own home if you prefer. *

Mobile service for Ultrasound Scanning is dependent on locality and
subject to additional cost for travel. Please enquire for details.
Ultrasound
is a reliable way to determine if a bitch is pregnant and therefore can
help breeders prepare for the oncoming litter.
The
number of pups can never be guaranteed as interpreting the scan imagery
can be difficult if the pups are lying on top of one another. There
is also a possibility that embryos can be re-absorbed quite late into the
pregnancy.
The
Science bit...
In
the dog, pregnancy does not necessarily begin on the day of mating.
During the canine reproductive cycle, oestrogen
will peak followed by the peak of the luteinising hormone (LH) 1 to 3 days later. Ovulation occurs 1
to 3 days after the LH peak.
The dog is
in oestrus or 'heat' starting at
the LH peak although this can be several days before or after.
Oestrus lasts 5 to 9 days during which time, breeding may occur on multiple
days. The male sperm remain fertile for 4
to 6 days.
All of these
variables result in an uncertain conception
date, and thus the apparent gestation length can vary from 56 to 72 days when counting
after the breeding date. The average canine gestation length is
approximately 65 days.
Ultrasound is a very sensitive and specific
imaging method to diagnose pregnancy if it is performed at least 30 days
after last mate. Pregnancy can be determined at 23 to 25 days post
mating but as the actual ovulation date is unknown, it is best to wait 30
days from last mate.
